MAXIM MAX4560EPE

19-1443; Rev 0; 4/99
±15kV ESD-Protected, Low-Voltage, CMOS
Analog Multiplexers/Switches
The MAX4558/MAX4559/MAX4560 are low-voltage,
CMOS analog ICs configured as an 8-to-1 multiplexer
(MAX4558), a dual 4-to-1 multiplexer (MAX4559), and a
triple single-pole/double-throw (SPDT) switch
(MAX4560). Each switch is protected against ±15kV
electrostatic discharge (ESD) shocks, without latchup
or damage.
These CMOS devices can operate continuously from
dual supplies of ±2V to ±6V or from a +2V to +12V single supply. Each switch can handle Rail-to-Rail® analog signals. The off-leakage current is only 1nA at
+25°C or 10nA at +85°C max.
All digital inputs have +0.8V to +2.4V logic thresholds,
ensuring TTL/CMOS-logic compatibility when using a
single +5V supply or dual ±5V supplies.

Note 1: Signals on any terminal exceeding VCC or VEE are clamped by internal diodes. Limit forward diode current to maximum current rating.
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

Note 2: The algebraic convention is used in this data sheet; the most negative value is shown in the minimum column.
Note 3: ∆RON = RON(MAX) - RON(MIN).
Note 4: Flatness is defined as the difference between the maximum and minimum value of on-resistance as measured over the
specified analog signal ranges; i.e., VON = 3V to 0 and 0 to -3V.
Note 5: Leakage parameters are 100% tested at the maximum-rated hot operating temperature and are guaranteed by correlation
at TA = +25°C.
Note 6: Guaranteed by design, not production tested.

±15kV ESD-Protected, Low-Voltage, CMOS
Analog Multiplexers/Switches
The MAX4558/MAX4559/MAX4560 are ESD protected
(per IEC 1000-4-2) at their X, Y, Z output pins and X_,
Y_, Z_ input pins. These ICs feature on-chip bidirectional silicon-controlled rectifiers (SCRs) between the protected pins and GND. The SCRs are normally off and
have a negligible effect on the switches’ performance.
During an ESD strike, the voltages at the protected pins
go Beyond-the-Rails™, causing the corresponding
SCR(s) to turn on in a few nanoseconds. This bypasses
the surge current safely to ground. This protection
method is superior to using diode clamps to the supplies. Unless the supplies are very carefully decoupled
through low-ESR capacitors, the ESD current through a
diode clamp could cause a significant spike in the supplies, which might damage or compromise the reliability of any other chip powered by those same supplies.
In addition to the SCRs at the ESD-protected pins,
these devices provide internal diodes connected to the
supplies. Resistors placed in series with these diodes
limit the current flowing into the supplies during an ESD
strike. The diodes protect the X, Y, Z and X_, Y_, Z_
pins from overvoltages due to improper power-supply
sequencing.
Once the SCR turns on because of an ESD strike, it
remains on until the current through it falls below its
“holding current.” The holding current is typically
110mA in the positive direction (current flowing into the
pin) and 95mA in the negative direction at room temperature (see SCR Holding Current vs. Temperature in
the Typical Operating Characteristics). The system
should be designed so that any sources connected to
the X, Y, Z or X_, Y_, Z_ pins are current limited to a
value below the holding current. This ensures that the
SCR turns off and normal operation resumes after an
ESD event.
Keep in mind that the holding currents vary significantly
with temperature; they drop to 70mA (typ) in the positive direction and 65mA (typ) in the negative direction,
at +85°C worst case. To guarantee turn-off of the SCRs
under all conditions, current limit the sources connected to these pins to not more than half of these typical
values. When the SCR is latched, the voltage across it
is about ±3V, depending on the polarity of the pin current. The supply voltages do not affect the holding currents appreciably. When one or more SCRs turn on
because of an ESD event, all switches in the part turn
off to prevent current through the switch(es) from sustaining latchup.
Even though most of the ESD current flows to GND
through the SCRs, a small portion of it goes into the
supplies. Therefore, it is a good idea to bypass the
supply pins with 100nF capacitors to the ground plane.

_______________Detailed Description
MAX4558/MAX4559/MAX4560
±15kV ESD-Protected, Low-Voltage, CMOS
Analog Multiplexers/Switches
ESD Test Conditions
ESD performance depends on several conditions.
Contact Maxim for a reliability report that documents
test setup, methodology, and results.
Human Body Model
Figure 6 shows the Human Body Model, and Figure 7
shows the current waveform it generates when discharged into a low impedance. This model consists of
a 100pF capacitor charged to the ESD voltage of interest, which is then discharged into the test device
through a 1.5kΩ resistor.
Power-Supply Considerations
The MAX4558/MAX4559/MAX4560 are typical of most
CMOS analog switches. They have three supply pins:
VCC, VEE, and GND. VCC and VEE drive the internal
CMOS switches and set the limits of the analog voltage
on every switch. Internal reverse ESD-protection diodes
connect between each analog signal pin and both VCC
and VEE. If any analog signal exceeds VCC or VEE, one
of these diodes conducts. The only currents drawn
from VCC or VEE during normal operation are the leakage currents of these ESD diodes.
Although the ESD diodes on a given signal pin are
identical and therefore fairly well balanced, they are
reverse biased differently. Each is biased by either VCC
or VEE and the analog signal. Their leakage currents
vary as the signal varies. The difference in the two
diode leakages to the VCC and VEE pins constitutes the
analog signal-path leakage current. All analog leakage
current flows between each input and one of the supply
10
terminals, not to the other switch terminal. This is why
both sides of a given switch can show leakage currents
of either the same or opposite polarity.
VCC and GND power the internal logic and logic-level
translators, and set the input logic limits. The logic-level
translators convert the logic levels into switched VCC
and VEE signals to drive the gates of the analog switch.
This drive signal is the only connection between the
logic supplies and logic signals and the analog supplies. V CC and V EE have ESD-protection diodes to
GND.
The logic-level thresholds are TTL/CMOS compatible
when VCC is +5V. As VCC rises, the threshold increases
slightly. When V CC reaches +12V, the threshold is
about 3.1V (above the TTL-guaranteed high-level minimum of 2.4V, but still compatible with CMOS outputs).
High-Frequency Performance
In 50Ω systems, signal response is reasonably flat up
to 50MHz (see Typical Operating Characteristics ).
Above 20MHz, the on response has several minor
peaks that are highly layout dependent. The problem is
not turning the switch on, but turning it off. The off-state
switch acts like a capacitor and passes higher frequencies with less attenuation. At 1MHz, off-isolation is
about -68dB in 50Ω systems, becoming worse (approximately 20dB per decade) as the frequency increases.
Higher circuit impedance also degrades off-isolation.
Adjacent channel attenuation is about 3dB above that
of a bare IC socket and is entirely due to capacitive
coupling.
